sAsrr-ornna'rme MECHANISM.

Application filed October 14, 1924. Serial No. 743,613. 1

Thepurpose of the invention is to pro- 'vide an effective device for the purpose of raising and lowering windows, particularly such as are used on closed vehicles; the device being susceptible of production in a cheap form so that it may be readily manufactured and, therefore, installed at small Cost.

l Vith this purpose in View, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein: t

Figure 1 is a front elevational viewof the invention appliedin operative position on a vehicle door. for the actuation of the window thereof.

Figure 2 is an enlarged detail sectional view on the line 2-2 of Figure 1.

The invention .is housed in the sash pocketand comprises an operating cable 1 traversing the upper and lower guide pulleys 2 and 3, the latter being rotatably mounted at the opposite ends of a base memher 4, preferably a casting, of cross sectionally channel torm to insure it against,

bending, and provided at the. upper end with a lateral ofl'set extension 5 carrying a pin '6 on which the gear 7 is rotatably mounted, the gear on opposite sides carrying the sheaves 8 and 9 consisting preferably of stamping riveted or otherwise secured to the gear. The extremities of the cable 1 a are secured one to one of the sheaves and the remainder to the other the sheaves being radially bored as indicated at 10, and

the terminals of the cable extending through;

said openings 10 for the reception by clamps 11 mounted on the gear within the peripheries of the sheaves. rotation of the gear will eflect longitudinal movement of the cable in one direction or the other depending upon the direction of rotation.

Obviously, the

The" gear 7 .is actuated .by'means or a pinion 12 rotatably'mounted on a spindle orpin 14 carried by v the base member 4 and by a bracket member 15 spanning the gear and securedto the base member by bolts or screws 16.- The spindle or pm 14 terminates in a crank 17 exteriorly exposed, that rotary movement may be imparted to the pinion and thus to the gear 7 and the sheaves carried thereby.

A. yielding latch is provided to retain the pinion in adjusted position and this latch consists of a spring 18 secured-to the base .men'iber 4 and provided witha nose 19 engaging between the teeth of the pinion- When thercrank 17 is turned, the latch mem:

her will be deflectedto permit rotation of the pinion and the gear, but upon cessation of the turning movement of the crank, the

latch member will engage between'the teeth of the pinion and prevent rotation of the latter under ordinary strain and thus will preclude rotation of the gear and arrest" movement oithe cable, with the result that the window with which the cable is opera tively connected is held at the desired adjustment. V

To retain theproper tension on the operating cable 1,. an idle roller.2O is provided and is rotatably mounted at the extremity of an arm 21 carried by the base member and pivotally connected with the latter,

pressure of the idle roller upon thecable being effected by means of a compression spring 22 telescoping a p1n 23 carried on the arm and a pin 24 of angular form and selectivel insertible in any one of a series of eyes 25 formed in the base member. Obviously, by theselection oi the desired eye 25, the pressure of the spring 22 may be regulated to secure the desired pressure of the idle roller.

The means for connecting the cable with 1 w the window consists of an angular plate 26 connected withthe web of the channel 27 I of the window frame, said angular plate be ing provided with a stud 28' disposed parallel to the flange connected with the channel and bored transversely tor the reception. of

a cotter pin 29 which'serves to retain the connector 30 in'place on the stud28, the

connector having an eye for pivotalflmove spring 31 in surrounding. relation with the.- stud and disposed between the connector and the plate, washers 32 being disposed bement with the stud, with a compression tween the springand the connectorand between the latter and the cotter pin.

The connector is of angular form, as

shown, and is secured to the operating cable by means of a clamp 33, the cable resting in the angle of the angular portion 3% ot the connector and the clamp spanning said angle and passing through a slot 35 formed in theangular portion having an angular extremity 36 to effect an nterlock between it andthe angular portion of the connector.

: A bolt 37 constitutes the means for securing the other end oi" the clamp'to the connector, the intermediate portion spanning the cable resting'in the angle of the angular portion 35 and said interinediate portion being transversely arched to provide 111) elements 38 for embedding in the cable and thus etiectively securing it in engagement with the connector. I

The invention having; been described what is claimed as new and useful is:

1,.'Incoinbination with a sliding window, a. base -1I1Qi'i1b81' having idler rolls at its extremities, a cable trained over said idler rolls and connected at an intermediate .point with said window,'a pair of sheaves mounted tor rotation on a common axis and 111 synchronism, and means for turning said sheaves, the sheaves being each radially bored and the extremities of the cable beingconnected one to each of the sheaves and extending through the bores and anchored on the sides thereof. 7

2. In combination with a sliding Window,

:a base member, idler rolls disposed at the extremities of said base member, a cable trained over the idler rolls'and operatively connected with the window, a cable actuating means consisting ota gear, sheaves dis-f with a yielding latch member engaging its teeth.

In testimony whereof he affixes his signatn re.
